The Oilers have four prospects competing at this year's IIHF World Junior Championship in Ostrava and Trinec, Czech Republic.
Eighth-overall pick from the 2019 NHL Draft, defenceman Philip Broberg, is suiting up for Sweden.
Also from the 2019 Draft, 38th-overall pick Raphael Lavoie is playing forward for Canada, joined by goaltender Olivier Rodrigue, who was selected 62nd overall in 2018.
The host Czechs feature forward Matej Blumel, whom the Oilers picked 100th overall at the 2019 Draft.
CANADA 6 SLOVAKIA 1
Canada cruised past Slovakia 6-1 in Thursday's quarterfinal round, atoning for last year's exit in the round of eight and advancing to semifinals as they aim to win the tournament for the second time in three years.
Arizona Coyotes prospect and Canada captain Barrett Hayton scored twice and added an assist in the victory, while Oilers prospect Raphael Lavoie had four shots on goal in 16:27 TOI but was held off the scoresheet.
Canada will now take on Finland in Saturday's semifinal round at 11am MT after the defending champions blanked the United States 1-0 in their quarterfinal matchup.
SWEDEN 5 CZECH REPUBLIC 0
Much like the Canada vs. Slovakia game earlier in the day, the other quarterfinal matchup involving Oilers prospects was one-sided as Philip Broberg's Swedes shut out Matej Blumel's host Czechs 5-0.
Vancouver Canucks prospect Nils Hoglander scored twice and had an assist to pace the Swedes, who are the only team that has yet to be defeated at this year's tournament.
Broberg played 17:26 for Tre Kronor in the win and had one shot on goal, while Blumel's tournament came to an end with 12:27 TOI and two shots. He finished with one goal, scored in the host squad's win over Russia, and will continue his season with HC Dynamo Pardubice.
Sweden will now face the Russians, who beat Switzerland 3-1 on Thursday, in Saturday's semifinals at 7am MT as they look to earn a medal for just the second time in six years.
